JOHN L. DINsMooR, or NEW Yofax, N. Y.

SEAL.

Application led June 27, 1921.

To all whom t may concern:

Be it known that I, J oHN L. DiNsMooR, a citizen of the United States, residing at the city of New York, borough of Manhattan, county and State of New York, have invented a new and useful Seal, of which the following is a specification.

This invention is a seal usually in the form of a strip of bendable material, said seal being adapted for use in connection with a large variety of structures or objects, such, for example, as car doors, electric and gas meters, shipping and price tags, and for the cords or other binders of shipping cases and packages.

In a device of this character, at least two factors are essential; first, to so fasten the two ends of the bendable strip that said fastened ends cannot be opened without detection, or, as it may be termed, picked, to open the seal and then refasten, either temporarily or permanently, without aifording evidence or leaving trace of the attempt to tamper with the seal; and, second, to give to the seal parts such form that the article is produced rapidly with a view to obtaining economy of manufacture without undue wear upon the tools required for the production of said article as well as to reduce to a minimum the number of operations required for such production.

A particularly desirable adaptation of my invention is in connectionwith tag and cord seals, in which forms of construction I use the bendable strip provided with a plurality o-f drawn seamless studs of the general charcessed or slotted for the accommodation of the cord, string, wire or other iexible element to adapt the seal for attachment to articles or for shipping packages, as well as to receive the two ends of a package binder composed of cord or other appropriate binding material.

For a tag seal, itis preferred to use a relatively short bendable strip provided intermediate the studs with an opening for the passage of the cord, the respective ends of which .are adapted to be received in a recess or slotof one of said studs. Whenapplying the seal to a tag, the recessed stud passes through an aperture in the tag, and the cord passes through the aperture of the seal strip, after which the strip is doubled to embrace the tag and for one stud to telescope the other stud and to enclose the cord. Com- Serial No. 480,508.

pressive force is now applied to the doubled strip for upsetting the metal of the studs and effecting the required interlocking of the two studs, the recess in one of said studs allowing the metal to be upset without cutting the cord. It is required that one of the two studs shall slightly exceed the diameter of the other stud, said studs being preferably cylindrical', whereby upon the assemblage of the studs into telescopic relation there is secured a binding contact of one stud with the other prior to the upsetting operation, thus precluding a separation of the one stud from the other at a time when the resistance of the doubled strip may have a tendency to pull them apart before the studs are upset.

Other functions and advantages of the invention will appear fromthe following description taken in connection ,with th drawings, wherein- Figure l is a plan View of the seal before closing adapted for use in conjunction with a tag or a cord or other flexible member.

Figure 2 is a longitudinal section through the seal and a part of the tag shown in Figure l.

Figure 3 is a vertical section through cooperating tubular studs of the seal shown in Figures 1 and 2, said figure illustrating the mode of telescopically assembling said tubu lar sides preliminarily to the application of compressive force.

Figure 4 is a sectional view on an enlarged scale of the seal shown in Figures 1 and 2 in a closed condition.

Figuresv 1 to 4 inclusive illustrate a practical form of seal adapted for use in conjunction with a shipping or marking tag E and a cord or other exible member F. The seal device comprises the metallic strip G of the required length and width. Said metallic strip G is provided near one end with a tubular stud H and near the other end with another tubular stud I. The studs H and I are seamless studs drawn from the metal of strip G so las to produce theindentations c in the respective edges of strip G, eac-h stud having a wall of less thickness than that of the metal composing the strip G, or the head of the stud. Strip G may be provided intermediate studs H I with an aperture g through which is adapted to pass a cord F or its-equivalent, and in the formation of the aperture g the metal is punched lor cut out of the s'trip G and is when the stud I is fitted over the stud H,l asdoubled or folded upon yit'self'so as to produce a tongue g', shown in Figure 2. The strip G is applied to tag E for the stud H to pass through a suitable opening provided in the tag,l thus disposing the strip Gr into Contact with one face of the tag, whereupon the ,tongue g is adapted to fold around the edge portion of the tag so that the tongue Vserves as a clip in the attachment ofn the strip G to the tag.

It is 'preferred to provide stud H with means for the reception of the cord or yeoluivalent iexible member F, and to this end said stud H is provided with a recess h, which recess opens through the top face of the stud and extends inwardly with re-f.

spect tothe stud for the desired distance; thus in Figure 3 the recess is extended practically to the base of the stud so as to produce a slot. The external diameter of stud H is slightly less than the internal diameter of the stud I,-whereby the stud H is adapted for the desired i'rictional contact with stud I when the two studs are assembled in z the telescopic relation shown in Figure 3..

The stud I preferably hasV the headv so formed as to produce therein a rib i, and

in Figure 3, the rib 'i of stud Iv enters the recess or slot h of stud H, thus expanding .the upper part 'of said stud H and securing a better interlocking engagement of the two studs when upset. By encasing the cord F in the recess of stud H, the cord is protected by the surrounding metal from the top of the stud H crushing inwardly and cutting the cord.

The mode of using the device ,is as follows: The strip Gr is placed against one side of the tag. for the stud H to pass through the opening therein and the tongue g is bent around the edge of the tag, thus securely attaching the sealing device to 'said tag. The cord or other flexible element passes through the aperture g of strip G and is adjusted or positioned Within therecess k of stud H. The operator now v.folds l or doubles the strip so .as to position the st-udvIover theV stud H and thecord, after which the seal press is manipulated orthe purpose of upsetting the metal composing the two studs, said compressing operation of the me'tal taking place as illustrated in Figure, 4 so as to avoid cutting the cord andto indent or depress the heads ofthe studs, at the same time interlocking one stud with the other for the/purpose of effecting a secure attachment ofthe sealingdevice to the tag. In the upsetting operation the rib 'i of stud I enters the outer end of the notch or recess in the stud H, thus closing the recess so as to prevent disengagement of the cord Aand the entry of thel rib into the recess operating to expand the stud I-I-within the Stud I.

Having thus fully described the invention,

4ing a foldable strip and two tubular stu s,

one 'of said studs being adapted to telescope over the other'of said studs, the inner lstud having a recess for the reception of a cord and the outer stud havnga depressed head whereby a downwardly reaching portion is .provided for entry into the recess of said inner stud whereby upon the application .of

compressive force to said studs said` downwardly reaching portion spreads the re- .1'- cessed stud.

In testimony whereof -I have hereto signed 90 -my name this 24th day of June, 1921.
